Does anyone have WHP and Torque numbers for 2006 997.1 GT3 3.6L?

Dyno sheet would be great help too.

I know the 05-07 3.6 motors are down 10-15 HP from the 08-09 spec 3.6.

Thanks

From a dynapack hub dyno (mine's an '06, 380.4 whp). Unfortunately the intake and muffler are not stock, so it may not suit your purposes.

Pete, thanks and your car is awesome.

From my research it seems that:

05-07 3.6 Cup: ~380 WHP
08-09 3.6 Cup: ~390 WHP (revised manifold and heads)
10-12 3.8 Cup: ~415 WHP

All with stock exhausts

Thanks...

Sounds about right for mine- I don't believe my muffler or intake are adding any power.

'08 has a different muffler as well with much larger tail pipes. I actually think the difference between the two models is bit more having driven a '07 and an '08 back to back. I think there is a couple hundred RPM difference in redline too. I noticed that at the Glen on back to back runs. A friend of mine who just had his '07 engine rebuilt wanted to upgrade to '08/'09 spec and the cost was $27k...

I think redline is 8200 for 06 and 08+ is 8500, but im not 100% sure on this.

There is not much of a cost difference between a rebuild on 06 to 09 specs and 3.8
